In a passive optical network, what role do optical splitters have?

Optical splitters play a crucial role in passive optical networks (PONs) by dividing optical signals among multiple fibers. This functionality is essential in a network environment where a single optical signal needs to be distributed to several end-users or devices.

In a PON, the optical splitter allows a single input fiber that carries data from the service provider to be split into several output fibers, which then connect to individual subscribers' premises. This division of the optical signal enables cost-effective sharing of the bandwidth among multiple users without needing additional active components like amplifiers or converters, which maintains the "passive" nature of the network.

Since a passive optical network does not require powered equipment in the path of the optical signal, the splitter's ability to manage and distribute the optical data efficiently is key to providing high-speed internet and other services to multiple customers from a single fiber feed.
